I just finished a new Down TQ to go with my 0° HG Incubator. This was my first quilt and I wanted to try something a little different. I was inspired by kduvey to do a Karo Step style. I figured it would be a good starter so I didn't have to worry about measuring the down. My down was in bulk. The measurements of the quilt are 54" X 74" and it has a 1/3 taper. I decided on a 8" karo size with a 4 1/2" long baffle. Because I wanted a match to my 0° UQ I used a 3 1/4" space for the baffle. (Baffle is 3 3/4" for seam allowance.)
I also wanted to try something different in the footbox area. All of the designs I had seen before just sewed in the footbox to the quilt. This allows for a "sewn through" type seam with no insulation. I thought about a draft collar to cover the seam but during the process I thought of making the foot box an actual box with the seam in the middle of the short sides. This would allow the seam to be covered on the inside and form against the quilt.
Here are some pictures of my progress:
